This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 1549280379. Listed at 24 retailers as of October 30, 2026, with prices from €3,384 to €7,736, a €4,352 spread on the same certified stone. NZ Jewellers lists it at €7,736. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
